Parse error: syntax error, unexpected '[' in /home/sites/http://ift.tt/21FRIMp on line 331

Here is my code :

<?php 
                    $exclude = ['diffusion','twice-loved','antique-vintage'];
                    $tax_slugs = [];

                    foreach ($tax as $value) {
                        array_push($tax_slugs, $value->slug);
                    }

                    $intersect = count(array_intersect($exclude, $tax_slugs));

                    //if( $tax[0]->slug != 'diffusion'): 
                    if($intersect === 0):

                    ?>
